In a complaint filed yesterday, a purported class alleges that Wal-Mart induced consumers to purchase Great Value brand parmesan cheese (billed as “100% Grated Parmesan Cheese”) despite the fact that it allegedly contained 7 to 10% cellulose, an anti-clumping agent derived from wood pulp. The complaint includes claims for deceptive practices and false advertising under New York law (as well as the laws of 40 other states and D.C.), breach of the implied warranty of merchantability, breach of the implied warranty of fitness for a particular purpose, and common law unjust enrichment.
